i got my sons passport when he was 5 weeks old and the shop that took the picture put a guarantee on it... if it got rejected by the passport office then they would re take the photos for free until it was excepted.

also the rules for photos of young children and babies aren't as strict as they are for adults my son was lead on a pillow for his photo which has got a shadow on it!

We had to get my daughter a passport when she was 3 weeks old. If you take your son to a snappy snaps, boots, walgreens, walmart, etc....they know exactly how to take the picture for your required country.
